DOOR-FASTENING DEVICE.

Specification of Letters Patent.

Application filed October 28, 1910.

To all whom it may concern:

Be it known that I, ROBERT A. MOORE, a citizen of the United States, anda resident of New York, county and State of New York, have inventedcertain new and useful Improvements in Door-Fastening Devices, of whichthe following is a full, clear, and exact speciication.

This invention relates to a class of de. vices for use in conjunctionwit-h a night latch to prevent the door of a building from being openedfrom the outside without the use of a suitable key to operate the latch.

My invention has for its object primarily to provide a form of fasteningdevice wherein is employed a movable bar adapted to be used in a mannerto effectually lock the door of a building or an apartment from theinside and which is adapted to coperate with any preferred form of nightlatch or lock whereby it will be impossible to force the door open fromthe outside thereof by the ordinary means used for such purposes, butwhich will permit said door to be readily opened by the personpossessing a key capable'of unlocking the latch or lock in use with thefastening device.

A further object of the invention is to provide a base plate to whichone end of the ar of my fastening device is swiveled and which isadapted to firmly hold said bar to the wall of the apartment inproximity to the stile of the frame to which the door is hinged; and toprovide means adapted to guide the free end of the bar so that it willengage with and be wedged under the slide bolt of the night lock whenthe door is closed.

A practical embodiment of the invention is represented in theaccompanying drawing forming a part of this specification in whichsimilar characters of reference indicate corresponding parts in all theviews, the said invention being more fully described hereinafter andthen pointed out in the appended claims,

In the drawing, Figure 1 is an elevation of a door and its frame partlybroken away wit-h one form of my improved door lock applied thereto.Fig. 2 illustrates the device attached to a wall at a right angle to thedoor. Fig. 3 is a side view of the bar and base-plate of the door lock.Fig.` 4: is a section through the base-plate and form of swivel forconnecting the bar to said base-plate, and Fig. 5 is a perspective viewof the guide for controlling the movement of the free end of the bar.

The door fastener 10 has a base-plate 11 which is adapted to beconnected by screws or in any suitable manner to a wall, as 12,preferably disposed at a right angle to the stile of the frame to whicha door 13 is hinged and upon the stile of the door opposite to the onehinged to its frame may be attached any preferred make of night lock orlatch, as 14:. To provide for proper cooperation of the night lock withthe door fastener 10 said lock is positioned so that the slide boltthereof will be disposed in the direction of the hinged edge of thedoor, that is, reversely to the usual manner of using a night lock.

The base-plate l1 may be of any desired form and to said base-plate isswiveled, as at 15, the member or arm 16 of a bar or locking element 17of the door fastener 10. The swivel 15 may be in the form of a ball andsocket, or a knuckle joint, but the form I prefer is to provide arecess, as 18, in one face of the base-platell and through saidbase-plate centrally of the recess 18 is an opening 19 in which isrotatably held the pin 20 of the boss 2Oa which is seated in the recess18 and extends from a flange or cap 21 of the swivel 15 which isprovided upon one end of the member or arm 16. To the opposite end ofthe member or arm 16 is hinged, as at 16a, one end of the bar or lockingelement 17 or this locking element may be connected in any other desiredmanner to said arm so as to permit the parts to move at any angle orupon any degree of a circle.

In order to lock the door 13 by the use of my device the bar or lockingelement 17 is disposed across the face of the door inside of the room orapartment and to allow for using one length of said bar upon doors ofvarious widths the opposite end of the bar 17 is interiorly threaded forreception of the threaded shank 22 of an adjusting member or pin 23.Upon the free end of the adjusting member or pin 28 is provided a heador knob 24 which is adapted to be wedged under the slide bolt of thenight lock 14 in locking the door 13 by the device.

It is evident that to open the door which islocked by my device, asdescribed, the slide bolt of the night lock l-ZL must be moved withinthe casing of said night lock from within the room or apartment orbyusing the key adaptedA to unlock the lock 14 from the outside of thedoor 13. 'When the slide bolt of the night lock 14 is moved fromengagement with the adjusting member or pin 23 the door 13 is pushed toan open position,

as indicated in dotted lines 25 Figs. 1 and 2, and the bar 17 willassume a proper angle by means of the hinge 16a, at the same timethermember or arm 16 will be turned ci'rl" justing-member 23 in abutmentwith said!- door and for the purpose of properly guiding the movementofthe adjusting member, 23 and said bar I provide a guiding element- 27.The guiding element 27 is provided withay base-plate or strip 28 whichis connected by screws or bolts 29 in a vertical position upon theinside face of the stile of the door 13 to which is attached the nightlock or latch 14 and the lower end of the strip 2 8 is held adjacent tosaid night lock; Formed upon one edge of the stri-p 28 is a projectingy:flange Vor Yright Yangle strip 30 which has a cut-out portion or isslotted, as at 31,'for passage therethrough of the slide ybolt ofthenight lock 14 s'o as to allow the knob 24 of the adjustingv member 23 tobe wedged thereunder; It isy clear, -that the movement of thellockingelement 17 willbe properlyr guided by Acontact of the adjusting'member 23 with the projecting flange or right angle strip 30 and toprevent the adjustin-g -memloer-123 against disengagement withthe`guiding'element27 when the door 13 is swung clearqopen a retainingmember Y or tube 3'2 is provided upon the upper end of the Ebase-plateor strip 28 and projecting fla-nge 30. The tubular member 32 ispreferablyv tapering A-in form to provide a `mouth 33 of greaterdiameter than the top port-ion thereofso yas to allow free access intothe interior 4of' said tiibular member of the adj iist ing member or pin23k of the locking element -or bar 1'7 when the door is opened. f Intheforegoing ldescription I have em-v bodied the preferred form of myinvent-ion, but Ido not 'wish to be understood as liinfiting myselfthereto, as Iainaware that modifications may -be made therein withoutdeparting from the principle or sacrificing any of the advantages .ofthis invention, there-v fore I Vreserve to myself the righttomake such-changesfas fallwi-tliin the scopel thereof.
